In plain words
Tunnelto.dev is an open-source tool built in Rust that creates public URLs for exposing localhost applications to the internet. It allows developers to quickly share web apps, APIs, or backend services running locally without deploying them. Users can access a free hosted version at tunnelto.dev or self-host the open-source code. The tool is designed to streamline the demo and testing process by eliminating deployment wait times.

Local development with .local domains and HTTPS2023 · localcan.com · ▲84Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS. It also has a reverse proxy that handles HTTPS termination and port forwarding. I'm working on adding more features, like an index page with all available domains or allowing proxy redirects, so you could redirect from HTTP to HTTPS. Let me know if you have any questions or feedback!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
